Motor-driven compressor

Abstract

A motor-driven compressor includes a wiring connection portion provided in a connector-receiving portion and adapted for supplying electricity from an external power source to a motor drive circuit. The wiring connection portion includes first and second terminals, each of which has a first end-connection portion at an end and a second end-connection portion at another end. The second end-connection portion of the first terminal is electrically connected to the external power source, while the second end-connection portion of the second terminal is electrically connected to a conductive member. The wiring connection portion further includes a coupling member coupling the first and second terminals. The coupling member includes a first metal plate connected to the first end-connection portion of the first terminal, a second metal plate connected to the first end-connection portion of the second terminal, and a wire mesh coupling the first and second metal plates.

1 . A motor-driven compressor, comprising:
 a housing;   a compression portion, an electric motor, and a motor drive circuit, which are accommodated in the housing;   a connector-receiving portion provided on an outer surface of the housing; and   a wiring connection portion provided in the connector-receiving portion, the wiring connection portion being adapted for supplying electricity from an external power source to the motor drive circuit; and   a conductive member provided in the motor drive circuit, the conductive member extending into a space in the connector-receiving portion and electrically connecting the motor drive circuit and the wiring connection portion with each other,   wherein the wiring connection portion includes
 a first terminal having a first end-connection portion at an end thereof and a second end-connection portion at another end thereof, the second end-connection portion being electrically connected to the external power source, 
 a second terminal having a first end-connection portion at an end thereof and a second end-connection portion at another end thereof, the second end-connection portion being electrically connected to the conductive member, and 
 a coupling member, which couples the first terminal with the second terminal, and 
   wherein the coupling member includes
 a first metal plate connected to the first end-connection portion of the first terminal, 
 a second metal plate connected to the first end-connection portion of the second terminal, and 
 a wire mesh connecting the first metal plate and the second metal plate with each other. 
   
     
     
         2 . The motor-driven compressor according to  claim 1 , wherein
 the connector-receiving portion is formed of metal, and   the motor-driven compressor further comprises an insulating member located between the wiring connection portion and the connector-receiving portion, which insulating member determines a position of the wiring connection portion in the connector-receiving portion.   
     
     
         3 . The motor-driven compressor according to  claim 1 , wherein the housing accommodates a rotary shaft having an axial direction, and wherein the connector-receiving portion extends in the axial direction of the rotary shaft and toward the electric motor. 
     
     
         4 . The motor-driven compressor according to  claim 3 , wherein the compression portion, the electric motor, and the motor drive circuit are accommodated in the housing to be arranged in that order in the axial direction of the rotary shaft.
